What is SEO Slug and Why Is It Vital for Your Site’s SEO Health?

What is SEO Slug

Slug 🐌… No, it is not this – 😀 It is the ‘name tag’ of a web page.

Although a name tag is the identity of any object or person. 

But surprisingly, this crucial ‘name tag’ often gets overlooked by many bloggers. Yet, it’s this very identity that can significantly influence your page’s SEO health.

Optimizing your slug might seem like a small task, but it’s an essential one. Think of it as giving your webpage a clear, memorable identity in the vast digital world.

Virtually, it’s not just about being found; it’s about being remembered and easily navigated back to.

Join us as we explore this often-underestimated aspect of SEO. 

You’ll be surprised how such a small part of your webpage can make a huge difference!

What is a Slug?

A slug refers to the part of a website’s address that explains the page’s content in a way that is readable by both users and search engines.

It’s the part of the URL that comes after the domain name, providing a concise description of the page’s content.

For example,


In this ‘URL’, the slug is  “saas-backlinks”.

This slug indicates that the page is likely about Link Building for SaaS.

Why Is Website Slug Important for SEO?

Website slugs play a pivotal role in SEO, acting as more than just part of your URL; they are key tools in boosting your site’s visibility and user experience.

A well-crafted slug turns a complex URL into something easy and clear. This helps users quickly grasp what your page is about, making them more likely to click and stay.

Including targeted keywords in your slug can significantly enhance your page’s search engine ranking. This is because search engines like Google use the slug to understand the content of your page.

But it’s not just about keywords and clarity. A good slug also:

  • Improves User Experience: Users often decide whether to click a link based on the URL. A clear and descriptive slug sets the right expectations, leading to a satisfied user who found what they were looking for.
  • Boosts Click-Through Rates: When your slug stands out with relevant keywords in search results, it attracts more clicks. People are drawn to URLs that directly address their search queries.
  • Supports Your SEO Strategy: Beyond individual page rankings, effective slugs contribute to your site’s overall SEO health. They are a small but significant piece of the larger SEO puzzle, helping your site gain traction in the crowded digital space.

Simple, clear, and keyword-rich slugs are the secret ingredients to making your website more accessible and attractive to both search engines and users.

How do you optimize your slug in WordPress?

Optimizing slugs in WordPress is a straightforward process integral to SEO and user navigation. This practice, essential for website management, ensures your URLs are both effective and functional for better online visibility and user engagement.

How to optimize your slug in WordPress

1. Include your focus keyphrase

Have you ever considered how important the words in your website’s URL can be? 

Including your focus keyphrase in your WordPress slug is like telling both search engines and visitors, ‘Hey, this is exactly what my page is about!’ 

It’s a straightforward yet powerful step in making your page easily findable and understandable.

  • Good URL Slug Example: For a page focused on ‘homemade pizza recipes’, an effective slug could be:


  • Bad URL Slug Example: However, a non-optimized slug lacks clear keywords and doesn’t tell users or search engines what the page is about.


By embedding your keyphrase in the slug, you make the URL informative and relevant, which enhances its appeal to both search engines and users looking for content on that specific topic.

2. Think about function words

When you’re crafting your slug, what do you think about function words or stop words like ‘and’, ‘or’, ‘but’? 

You might be surprised, but they’re not always necessary. In fact, it’s often better to leave them out. 

These small words don’t usually add value to your SEO and can make your URL unnecessarily long.

  • Good URL Slug Example: For an article titled “Tips and Tricks for Gardening”, a streamlined slug could be


  • Bad URL Slug Example: A less optimized slug is longer and includes unnecessary function words.


By trimming these function words from your slug, you’re making your URL cleaner and more concise. 

This not only makes it easier for users to remember and type, but it also helps search engines to focus on the important keywords, improving the clarity and effectiveness of your SEO efforts.

3. Be Descriptive

When you’re browsing online, aren’t you more likely to click on a URL that tells you exactly what to expect? That’s where being descriptive with your slug comes in. In WordPress, your slug should give a clear, concise preview of your content.

  • Good URL Slug Example: For an article about ‘tips for beginner gardeners’, a descriptive slug would be:


  • Bad URL Slug Example: On the flip side, a vague slug doesn’t provide any clues about the content, which can be a turn-off for both users and search engines.


By crafting a slug that’s descriptive, you not only enhance user experience but also improve your content’s searchability. It’s like giving your page a little introduction before the reader even clicks the link, making it more inviting and relevant.

4. Make It Concise and Easy to Read

Ever noticed how the best URLs are short and sweet? That’s exactly what your WordPress slug should be too! Making your slug concise and easy to read is like giving your page a clear, friendly signpost.

  • Good URL Slug Example: Imagine a page about ‘organic gardening tips’. A slug is short, to the point, and easy to understand.


  • Bad URL Slug Example: On the other hand, following slug is overly long and confusing:


A shorter slug isn’t just about brevity; it’s about clarity. A clear, concise slug makes it easier for users to remember and type, and for search engines to parse. It’s like giving directions – the clearer you are, the easier it is for someone to follow!

5. Use Lowercase Characters

Have you noticed that most URLs are in lowercase? There’s a good reason for it. When it comes to creating your WordPress slug, sticking to lowercase characters is a smart move. Why? Because URLs are case-sensitive.

  • Good URL Slug Example: Opt for something like the following slug instead of using any uppercase letters:


  • Bad URL Slug Example: A slug like below might look neat, but it can cause confusion and errors, especially if users type it in all lowercase by habit.


Using lowercase letters in your slugs avoids this confusion and ensures that your links always lead where they’re supposed to, no matter how someone types them.

6. Avoid Special Characters

Special characters in your URL slug can create a mess! It’s true! Characters like &, %, $, and @ can confuse both search engines and users. They make your URLs look complex and uninviting.

  • Good URL Slug Example: A clean slug is straightforward and user-friendly.


  • Bad URL Slug Example: On the other hand, some slug can be off-putting due to the special characters, making it less likely to be clicked or shared.


Sticking to letters and hyphens keeps your slugs neat and understandable. This approach not only makes your URLs cleaner but also ensures they are easily crawlable by search engines and memorable for users.

7. Use Hyphens, Not Underscores

When creating your slug in WordPress, it’s important to use hyphens (-) instead of underscores (_). Why, you ask? Well, search engines like Google treat hyphens as space, but they don’t recognize underscores in the same way.

  • Good URL Slug Example: This slug uses hyphens, making each word distinct and easily readable by search engines.


  • Bad URL Slug Example: This slug with underscores isn’t as SEO-friendly. Search engines might read it as one long word.


When separating words in your slug, stick to hyphens. This small tweak can make a big difference in how search engines understand and index your page, ultimately helping your SEO.

8. Make It Future-Proof

Most bloggers have this question in mind – How to keep your WordPress slug relevant for years to come? The trick is to make it future-proof. This means avoiding dates or fleeting trends in your slug, focusing instead on timeless, enduring terms.

  • Good URL Slug Example: For an article on sustainable living tips, a future proof slug might be:


  • Bad URL Slug Example: In contrast, this slug might quickly become outdated.


By choosing a slug that remains relevant regardless of time, you ensure your content continues to attract visitors long-term. It’s like picking a classic wardrobe piece over a fleeting fashion trend – it never goes out of style!
